Summary
This study explores electrospray as a way of decorating cellulose tissues with chitin nanofibrils, comparing two very different sources of the same nanomaterial: crustacean shells and fungal biomass. Several solvent systems were tested, and in every case the nanofibrils formed a uniform coating over the cellulose surface. Biological testing on human dermal keratinocytes indicated that all the treated tissues were compatible with skin contact, supporting the use of biowaste-derived nanomaterials in cosmetic and skincare products. The work is part of a wider effort to build fully biobased, skin-compatible materials using surface functionalisation rather than bulk reformulation.
